On one day, the temperature on a hill at 7 p.m. was `6^(@)C` but at a mid - night, it fell down to `-4^(@)C` . By how many degrees did the temperature fall ?

Options

A. `5^(@)C`
B. `6^(@)C`
C. `7^(@)C`
D. `10^(@)C`

Answer

To find out by how many degrees the temperature fell from 7 p.m. to midnight, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the temperatures at the two times:**
- Temperature at 7 p.m. = 6°C
- Temperature at midnight = -4°C

2. **Set up the equation to find the temperature difference:**
- Temperature difference = Temperature at 7 p.m. - Temperature at midnight

3. **Substitute the known values into the equation:**
- Temperature difference = 6°C - (-4°C)

4. **Simplify the equation:**
- When subtracting a negative number, it is the same as adding the positive number.
- Therefore, Temperature difference = 6°C + 4°C

5. **Calculate the final result:**
- Temperature difference = 10°C

### Final Answer:
The temperature fell by 10°C.
